OneKDP AI book and cover generator is a web-based workspace for independent authors, publishers, and creators preparing books for Amazon KDP. It uses AI to turn a brief into editable book interiors, print covers, or a complete book project while keeping users in control of writing, layout, and design decisions. Users can create novels, workbooks, coloring books, puzzle books, journals, planners, and activity books by selecting the book type, language, trim size, audience, and production details. The KDP book cover generator produces front, spine, and back print wraps based on page count and paper settings, while the book editor supports text and page revisions. Manual editing, cover refinement, preflight checks, trim and bleed inspection, keyword-volume research, and separate PDF exports help prepare files for KDP upload. OneKDP brings AI book creation, cover design, editing, and publishing file preparation into one workflow instead of requiring separate design and formatting tools. Free calculators, editors, and exports are available, while AI generation uses a credit-based pricing model. It is designed to help creators move from an idea to reviewable KDP-ready files.

AI Hairstyle Changer, an AI hairstyle changer, is a browser-based virtual makeover tool that lets people preview haircuts, hairstyles, and colors on their own photo. It is designed for anyone planning a salon visit who wants to compare possible looks before making a real change. Users can upload a front-facing JPEG, PNG, or WebP portrait up to 10 MB and explore more than 100 hairstyles, including bobs, bangs, pixie cuts, waves, braids, updos, and layered looks. The tool supports solid colors and root-to-tip gradients, reference-photo hairstyle try-ons, before-and-after comparisons, downloadable previews, and an optional AI Styling Advisor with personalized suggestions. Signed-in users can compare multiple generated looks from the same image using credits. AI Hairstyle Changer helps users communicate preferred length, shape, texture, and color direction to a stylist with visual examples. It requires no app installation and offers one limited free guest preview, while additional generations use purchased credits; results are visual simulations rather than guarantees of real salon outcomes.

ChatSweep ChatGPT bulk delete is a Chrome extension for cleaning up conversations in ChatGPT without removing chats one by one. It helps ChatGPT users, researchers, writers, and teams select loaded sidebar conversations, review them, and delete or archive multiple chats from a single panel. The current conversation is protected during cleanup. Users can display checkboxes beside loaded ChatGPT chats, filter and select conversations, review the batch, then confirm a bulk delete or bulk archive action. ChatSweep supports ChatGPT chat management, mass deleting conversations, and organizing chat history by clearing temporary questions, old drafts, and completed projects. It works with chats already loaded in the sidebar, includes confirmation steps and compatibility checks, and pauses when page controls cannot be verified. The free plan supports one cleanup per day and up to 10 chats per run, while paid plans remove those limits and add bulk archiving. ChatSweep reduces repetitive sidebar clicks while keeping deletion deliberate and protecting the open conversation. Cleanup takes place in the browser, and deleted chats may not be recoverable, so users can review every batch before confirming. It is an independent Chrome extension for maintaining a more manageable ChatGPT workspace.

TwitterViewer is a Twitter viewer for reading public X posts, profiles, threads, replies and media without an account or login. Users can paste an x.com or twitter.com post URL, enter an @username, or search by hashtag to access publicly available content in a clean web interface. It is designed for people who want to view Twitter content without creating an X account, installing an extension, or sharing login credentials. The platform includes a Twitter profile viewer for bios, follower counts, posts, replies and pinned content, plus a media viewer for photos, videos and GIFs. Users can open full threads, read public replies, view quoted posts, unroll an author’s posts, copy thread text and export threads to PDF. The Twitter video downloader supports available MP4 quality options, while advanced search, people search, a location checker and an X Communities exporter provide additional ways to find and organize public information. Public lookups work without an account, while deeper replies and selected account-connected features require a paid plan. TwitterViewer provides a simple way to read public X content while avoiding sign-in walls, advertisements and third-party tracking. It does not bypass protected accounts, deleted posts or private content, and its main distinction is a focused, no-login reading experience for desktop and mobile users.

Seply is a browser-based AI audio tool designed to separate speakers from mixed recordings.

Seply also provides speech-to-text transcription with speaker labels, timestamps, and TXT, SRT, VTT, or JSON exports. No software installation is required, and new users receive 20 free credits.
